a Tandem-like PEC cell composed of BiVO4 photoanode decorated with Zn-doped CuInS2 (ZCIS) QDs and a Cu2O photocathode decorated with ZCIS QDs. b Schematic illustration of type-II and p–n heterojunctions formed in BiVO₄–ZCIS QDs and Cu₂O–ZCIS QDs photoelectrodes, respectively. c Nyquist plots of ZCIS QDs capped with different organic ligands (ZCISLigand). d, e Photoluminescence spectra of ZCIS QDs capped with d DDT and e MPA, each measured both in solution and as thin-film electrodes.
